Abstract (en)
[origin: WO0077463A1] A self contained cooling apparatus (60) in a pressurized beverage container (10) includes an outer at least partially compressible housing (62, 103) which contains a liquid and is sealed by a diaphragm (66) and an inner breakable housing (64, 90) which contains a sorbent (29) mixed with a phase change material (29). When the container (10) is opened the pressure falls whereby the diaphragm (66) which was pushed inwardly returns and fractures the shell of the inner housing (64, 90) thereby exposing the sorbent (28) to the liquid which by evaporating cools the beverage. The diaphragm (66) can be kept in its pushed-in state by a torsionally twistable bridge (68), a dissolvable column (111) or a spring (115) held by a dissolvable latch (117).
